Spring locale resolver - current locale in url - spring-mvc

I use this simple configuration
<beans:bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<beans:property name="basename" value="classpath:localization/messages" />
<beans:property name="defaultEncoding" value="UTF-8" />
</beans:bean>
<interceptors>
<beans:bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<beans:property name="paramName" value="lang" />
</beans:bean>
</interceptors>
<beans:bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver">
<beans:property name="defaultLocale" value="en" />
<beans:property name="cookieMaxAge" value="100000" />
</beans:bean>
Works nice but what if someone will send an url to someone else? This works only with a client browser, If user changes a localization, it will set a cookie. I have seen a lot of websites that they have a localization after the first slash in the url (e.g. nette.org/en/about). When someone send this link, it will resolve localization depending on url. Does exist any simple solution to do this in spring framework? Somehow map this place in url?

Instead of CookieLocaleResolver use SessionLocaleResolver.
<bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
<property name="defaultLocale" value="en"/>
</bean>
I think this should resolve your problem.
Cheers.

spring security logout success url redirecting to http from https

Our application is protected by siteminder web agent and is on https.
Our application is running on weblogic and is on http.
When the user access protected URL, the siteminder login page(https) is displayed and the user enters his credentials here.
But after successful authentication, the user was redirected to http URL and page cannot be displayed or unable to connect message was displayed.
I fixed this issue by adding redirectHttp10Compatible="false" attribute to my view resolver.
Now, upon logout, the application is redirecting to logout success URL over http rather than https.
redirectHttp10Compatible="false" attribute is still in the same place.
Any help in this regard is very helpful and highly appreciated.
Thanks a lot in advance.

Metadata External xml Path Issue

I would like to read the metadata from the external xml file in my saml configuration . Can anybody tell me whether it is possible or not . if yes then how?
currently i tried with this:-
grails.plugins.springsecurity.saml.metadata.sp.file = 'file:c://temp/idp_local.xml'
In my web project I put metadata in resources under src directory. Content gets deployed inside WEB-INF/classes in the final WAR.
In your spring security configuration file you can then use this code for example:
<beans:bean class="org.springframework.security.saml.metadata.ExtendedMetadataDelegate">
<beans:constructor-arg>
<beans:bean class="org.opensaml.saml2.metadata.provider.ResourceBackedMetadataProvider">
<beans:constructor-arg>
<beans:bean class="java.util.Timer"/>
</beans:constructor-arg>
<beans:constructor-arg>
<beans:bean class="org.opensaml.util.resource.ClasspathResource">
<beans:constructor-arg value="/metadata/TestFederationMetadata.xml"/>
</beans:bean>
</beans:constructor-arg>
<beans:property name="parserPool" ref="parserPool"/>
</beans:bean>
</beans:constructor-arg>
<beans:constructor-arg>
<beans:bean class="org.springframework.security.saml.metadata.ExtendedMetadata"/>
</beans:constructor-arg>
<beans:property name="metadataTrustCheck" value="false"/>
</beans:bean>

In Spring MVC 3 local is not getting changed when clicking local changing link

I have set up i18n to my Spring MVC project . The language is not changing when I click on the link:
Hindi
English

<context:component-scan base-package="com.avvas.search.controller" />

local changing links:
Hindi
English
The issue is that when i click on hindi the page should be displayed in Hindi language, Language is not getting changed. However i changed default language to hindi <property name="defaultLocale" value="hi"/> then it is taking local as hindi but when i click on english local change link the local is not getting changed.
<mvc:annotation-driven/> is registering its own handler mapping (RequestMappingHandlerMapping) and your interceptor configuration is not applied to that.
Define your interceptor like this:
<mvc:interceptors>
<bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="lang" />
</bean>
</mvc:interceptors>
Here is the Complete code. Basically we need to register our interceptors explicitly.
<bean id="localeChangeInterceptor"
class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="lang" />
In above given xml you have given "localeChangeInterceptor" but you haven't mentioned anywhere that it should intercept all the requests by default.
So Spring will load all the beans but it wouldn't register it as interceptor until or unless you define that which requests it should intercept.
In below example i am defining it in mvc interceptor and telling the framework that it should consult that interceptor before processing any request.
<mvc:interceptor>
<mvc:mapping path="/**/**/" />
<bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="locale" />
</bean>
</mvc:interceptor>
</mvc:interceptors>

spring generating wrong path to forward

I have added view resolver to my spring-servlet.xml like this
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property>
<property name="suffix" value="/WEB-INF/jsp/"></property>
<property name="prefix" value=".jsp"></property>
</bean>
but when i'm running my web application it returns a wrong path as shown in log
Forwarding to resource [.jsphello/WEB-INF/jsp/] in InternalResourceView 'hello'
whereas it should be WEB-INF/jsp/hello.jsp
Why is this happening?
Switch prefix and suffix in your configuration:
<property name="prefix" value="/WEB-INF/jsp/"></property>
<property name="suffix" value=".jsp"></property>
Then it will result in:
/WEB-INF/jsp/hello.jsp
Prefix always goes before, while suffix goes after.

Spring MVC 3 Locale changing using a link not working

Edit: My Spring framework version 3.0.5
A small issue here, The language is not changing when I click the language changer link.
The language files (messages_xx.properties) are in the classpath i18n directory. The files are:
i18n/messages_en.properties
i18n/messages_ar.properties

<property name="defaultEncoding" value="UTF-8"/>
</bean>
A section from the JSP Code
<spring:message code="header.arabic" /> |
<spring:message code="header.english" />
The issue is, when I click the above link to change the language, the locale changing functionality is not working. I tested by changing the "defaultLocate" to "ar" and I'm getting Arabic text.
What could possibly be wrong here? There is nothing in the tomcat log also.
You have to register the localeChangeInterceptor among the MVC interceptors for Spring-MVC to consider it. Add the interceptor to the configuration:
<mvc:interceptors>
<bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="lang"></property>
</bean>
</mvc:interceptors>
<mvc:interceptors>
<bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor"
p:paramName="lang" />
</mvc:interceptors>
<bean id="localeResolver"
class="org.springframework.web.servlet.i18n.CookieLocaleResolver">
<property name="defaultLocale" value="en" />
</bean>
Another thing that can help others:
In my case, I MUST add in the applicationContext.xml. Putting it in the spring-servlet (ref. dispatcher), not worked at all.
You need to register the LocaleChangeInterceptor inside the mvc interceptors tag as below,
E.g.
<mvc:interceptors>
<bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="siteLanguage" />
</bean>
</mvc:interceptors>
I was getting the same error and it worked using this code :-)
